"[Dvoretsky and Pervakov] have written a book valuable for those who want to train and for those who love beauty in chess...The book is just what it purports to be...You will find text aplenty, offering explanations, a discussion of themes, aesthetics, applications to and analogies with over the board play, and more besides. A further interesting feature is the final, 47-page chapter, which presents studies not by the professionals of composition but by practical players (most of the world champions, and a number of top-class grandmasters from Tarrasch to Morozevich). This book too I can highly recommend, and have already been working with the original, Russian-language edition for some time." Dennis Monokroussos at ChessMind.com
